Technological
Practice
Students
will:
Planning
for practice
*
Undertake planning to identify the situation in Papua New Guinea
and the knowledge and resources required to develop a method
of washing hands using very little water.
Brief
development
*
Describe possible solutions to the hand washing problem explaining
how they could address the need.
* Investigate the context of PNG students in highland schools
to develop ideas for potential outcomes. Trial and evaluate
these against key attributes (see below) to select and develop
an outcome to address the need. Evaluate this outcome against
the key attributes and how it addresses the need.
Technological
Knowledge
Students
will:
Technological
modelling
*
Design a prototype for a device that can be used to evaluate
the fitness of purpose backed up with educational material on
sanitation education.
Technological products
* Test the materials used for their performance properties for
fitness of purpose.
Nature
of Technology
Students
will:
Characteristics
of technology
*
Understand how Papua New Guinea society and school environment
impact on and are influenced by technology comparing PNG to
New Zealand.
* Characteristics of technological outcomes
Understand that technological outcomes are recognisable as fit
for purpose by the relationship between their physical and functional
natures.
Key
attributes:
1.
School water tanks often only provide half a litre of clean
water per student per day.
2. Water can only be collected from metal roofs. Some schools
have a thatched roof making water collection impossible.
3. River water is often contaminated and located a long way
from the school.
4. There is very little water to wash hands.
5. Very few schools have hand washing facilities and until recently,
only a few of the schools had toilets.
6. The schools do not collect enough school fees to build enough
toilets and hand-washing facilities for students and the government
provides little assistance.
7. Unfortunately, the high incidence of typhoid and other diseases
are a result of the lack of hand washing facilities.
8. There are almost no health education materials in the schools.
